Additional Notes
- The Fiat 1300/1500(S)/1600S cooling system specifications cover variants produced from 1959-1967, with capacity figures representing the total volume of the closed cooling circuit, including the radiator, engine block passages, and heater core where fitted.
- Four of the five listed variants share a cooling system capacity of 6.7 liters under normal use conditions, applying to the 1300/116, 1500/115, 1500 Coupe/Cabriolet 118H/K, and 1600S Coupe/Cabriolet 118SA/SB configurations.
- The 1500S Cabriolet 118S, produced from 1959-1963, carries a slightly lower cooling system capacity of 6 liters under normal use conditions, making it the only variant in the group to fall below the 6.7-liter figure.
- The 0.7-liter difference between the 1500S Cabriolet 118S at 6 liters and the later 1500/115 at 6.7 liters, despite both being 1500-series engines, reflects a change introduced alongside the model transition that began in 1961.
- The 1500S Cabriolet 118S is also the earliest variant in the specifications, with a production window starting in 1959, predating the 1961 introduction of the 1300/116 and 1500/115 configurations.
- All five variants list normal use conditions, meaning the 6 and 6.7-liter capacities apply to standard operating environments rather than severe-duty or first-change-only scenarios.
